It seems that is correct and Windows, at least in some configurations,
only proposed modp1024 in IKEv2, which libreswan no longer allows in its
default proposal. You will need an ike= line that matches the windows
proposal, possibly: ike=aes128-sha1;modp1024

You need to fix the ike= line, not the esp= line.
